STUD FOR BUILDING CONSTRUCTION.

srno'zsrca'rron forming part of Letters Patent No. 682,316, datedseptember 10, 1901. Application filed September 15, 1900. Serial No.305120. (No model.)

To aZl whom, it may concern:

Be it known that I, WILLIAM L. CALDWELL, a citizen of the United States,residing at New York, in the county and State of New York, have inventedcertain new and useful Improvements in Studs for Building Construction,of which the followingis aspecification.

This invention relates to improvements in studs for buildingconstruction adapted for use with perforate sheets or open-Work metallathing, particularly the expanded metal or similar lathing now in usefor fireproof construction.

The invention consists in a stud or strip of rolled metal or othersuitable malleable material with projections formed thereon andtherefrom by punching through the metal of the stud, leaving the punchedportion attached along one edge or end and with metal on both sidesthereof and bending it out to form a projection, tongue, or prongcapable of passing through a perforation in the metal lathing andengaging with the lathing to support same and adapted to be bent back orover the lathing, so. as to hook or clench same firmly in place.

In the accompanying drawings, Figure 1 is a perspective View of a studprovided with my invention. Fig. 2 shows the studs with a portion ofmetal lathing in. place thereon, the view being taken in front, butlooking down at an angle on the structure. Fig. 3 is a vertical sectionof the stud and lathing from front to back. Figs. 4 to 6 show theapplication of the invention to various forms of stud or strip.

Referring to Fig. 1, a stud of rolled malleable'metal is represented at1, with flat face portions 2, connected by a doubled or folded centralportion 2, this latter portion being preferably not bent into closecontact, but kept somewhat open at the bend 3, so as not to crack themetal by too sharp bonding.

The flat face portion of metal stud 1 is punched or slit at a number ofplaces, forming a plurality of prongs or tongues 4, which are allowed toadhere to the stock at one edge or end. These prongs are bent out eitherat the time of punching or afterward to form projections and leavingholes 5 in the stud with metal on both sides of the hole or of theprong, so that the stud is not materially weakened. The prongs may bepunched up from any portion of the studthat is, sufficiently removedfrom the edge and sufficiently thin-but they are preferably punched froma flat portion of the stud.

The studs having been set up in position, the metallic perforate lathingis attached thereto,as shown in Figs. 2 and 3,the said lathing(represented at 6) being placed against the studs 7 and the prongs 4passing through the perforations in the lathing and engaging with theribs thereof to support the same. The tongues or prongs 4 beingmalleable may then be upset or bent over or backward, so as to clenchthe lathing to the post.

Fig. 4 shows a furring-strip for side walls or ceilings, Fig. 5 anangle-stud, and Fig. 6 a box-stud, all provided with prongs 4 forengaging and supporting the metallic lathing. In the form of myinvention shownin Fig. 4 the groove portion or longitudinal loop portionof the furringstrip is the part that is provided with projecting tonguesor tangs 4 and the sides of the loop, which are separated, as shown,terminate in lateral flanges.

Studs may be shipped with the prongs unbent, so as to prevent injury;but by properly stacking the studs in shipment they may be safelyshipped with the prongs bent out, and for convenience it is preferableto furnish them in this condition.

That I claim as new, and desire to secure by Letters Patent, is-- 1. Abuilding construction comprising perforate metallic lathing and a studof malleable metal with flat prongs formedl thereon and therefrom bymaking perforations in the fiat portion of the metal strip so that theprongs are supported at one end and have metal on each side of them projectin g through perforations in the lathing and bent over the latter soas to clench same.

2. A stud for partitions comprising a longitudinal loop portion, theedges of which are separate, lateral flanges at said edges and loopportion.

3. A stud for partitions comprising a 1ongitudinal loop portion, theedges of which are separate one from the other, lateral flanges providedat said edges, and means in the 5 said loop portion by which Wire orother lath may be secured to said 100p portion.

4:- A stud for partitions comprising a 1011- 1 gitudinal loop portionand means provided therein by which Wire or other lath may be securedthereto.

llt is hereby certified that in Letters Patent No. 682,316, grantedSeptember 10,

1901, upon the application of William L. Caldwell, of New York, N. Y.,for an improvement in Studs for Building Construction, an error appearsin the printed specification requiring correction as follows: Page 1,line 93, claim 1, before the word projecting insert a comma; and thatthe said Letters Patent should be read with this correction therein thatthe same may conform to the record of the case in the Patent Ofiice.
